Meth nozzles locations ?
Well, I would like to know how many nozzles should I used and where are the locations of the nozzles and sizes?
I have seen Shardul post with pics on other forum, from the pics, I could understood that the nozzles are placed after the S/C IC right?
No nozzle should be placed before S/C?
I need to know this information as soon as possible please.
With the supercharged E55 though and how the throttle body and supercharger arrangement are you would want to not place the nozzle before the throttle since it would be compressed in the charger. When running pre turbo or supercharger you want to use a very small nozzle and it helps to make the compressor map a little fatter and have them run more efficient. On the other hand you aren't going to get as good of a result as if you were to run a larger nozzle after the supercharger in these cars though since with the larger nozzle you will have a greater chance of cooling the intake air temps right before it enter the cylinders as well as injecting more methanol into the combustion chambers.
You want to be sure that the nozzle(s) are before the intake air temp sensor though to get the benefits of not only having the engine run cooler and safer from detontation protection, but also gain the performance of the ecu increasing ignition timing due to the temperature sensor reading cooler intake temps.
So in conclusion you want your nozzle to be after the supercharger and before the intake air temp sensor and typically they would be placed after the intercooler setup which in these cars gives very little room and options since the intake temp sensor is so close after the intercooler.

Mine personally is about 8" before my throttle body (the IAT sensor is in the intake manifold immediately after the throttle body housing). Many many others all run theirs literally right before the throttle body and even in special plates that bolt behind the throttle body about 1" before the sensor with great success. Here is an example of the plate (doing it this way behind the throttle body is recommended to use a solenoid to keep from syphoning under vacuum) and the sensor is that black thing right behind the plate on the right side of the manifold inlet hiding under the red hose.

So as you can see that type of setup is only 1" away from the sensor and works perfectly so 4" is obviously better and sufficient in my book. In my opinion the channels of the intercooler would interfere with atomization and cause the water to want to stick more instead.
As for nozzle sizes, I have a little over 400whp (all wheel drive) in my Audi and run a 625cc nozzle and some guys running around 500 or just over even run as high as the 900cc range. My car with the meth turned off has trouble with rising intake air temps and with it on is dramatically different so I believe with something in the 600-700cc range on an E55 with similar power levels of 400-500whp you will have great results.
I am out of town for work at the moment and when I get back plan on installing a kit on the E55.

Now it is tricky and hesitating, coz the guys are running directly after IC and on the surge tank (The one that has the word AMG).
That's confusing

Location 1 to me is best as atomisation is best and also this is where heat is the highest in the ar flow, and this is where you get best cooling effect.
Location 2 also works but you are directly opposite the MAP sensor and I am concerned this could lead to erratic MAP readings when you are pulsing. The IAT sensor also has chance to get wet and wet bulb read could mess up things as well, also atomisation is less efficient here....
Using Aquamist HFS6 with one 0.8mm jet at 130PSI, kicks in at 70% IDC and ramps up to max fow at 95% IDC. I am thinking of adding some curve for MAP as well now.
If anyone need to know the ECU pinpouts for connections its like this...
Socket 3, location 27 for IDC
Socket 5, location 9 for ignition on (prime)
Socket 3, pin 10 for MAP

Hope this helps
Ive tried one nozzle and two, Ive had it pre IC and post and my current is a M3 pre TB and a #7 pre IC. the difference is around 30 degrees having it pre IC vs Post, I moved mine for 2 reasons, one I wanted a more accurate picture of IAT temps and also I had gone through 2 map sensors in a years time frame.




Size of the nozzle is 550 cc and I don't know if that's enough or not but at least i am getting something.


Nick and I have worked very closely progressing his meth set up and, considering the amount of meth kits I have done, this is the best nozzle location. M3 in the tb housing and M7 before the intercooler.
Guys- this is not speculation like a couple of the posts in this thread, These are tried and true solutions to the dual nozzle placement location.

Bottom of the line, one nozzle = either before IC or after IC.
Please someone corrects if i am wrong.





Well I dunno I certainly would not want to be spraying meth & water into the S/C screws...
I use one 0.8mm jet ahead of I/C, in the elbow after the s/c outlet. This is the best location for one jet.
YMMV.

so the meth wont harm S/C screws ??
